COIN-ACTUAT'ED MACHINE.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed February 10, 1919. Serial No. 276,084.

To all whom it may concern:

. Be it known that 1, CHARLES LAURENCE 'BURDICK, a citizen of the UnitedStates of America, residing at d Eastern TOflCL'VVOOCl Green, London,England, have invented new and useful Improvements in Coin-Actuated-Machines, of which thefollowing is a speciify the constructiondescribed in the said former specification in the following manner, thatis to say, I combine with the bolt which secures the coin receptacle alock which secures the bolt and which is so constructed that the key ofsuch lock cannot be removed after the bolt is withdrawn until the bolthas been returned to secure the said coin receptacle. Also Iadvantageously provide for introducing separate slips of paper into themachine as foreshadowed in the said earlier specification, but I nowarrange that the insertion of these slips will practically form a partof the operation of unlocking the machine to enable the withdrawal ofthe coin recepectacle, that is to say, I provide in connection with thelook a stop which prevents the complete insertion of the key into thelock until the said stop has been removed by the introduction of thepaper. I furthermore provide that the longitudinal movement of this boltafter it has been unlocked shall effect the operation of the printingmechanism, and that the return of such bolt toits lockin position shallset the numbering disks back to zero.

In the accompanying drawings Figure 1 is a'sectional plan of theimproved apparatus.

Fig.2" is a sectional end elevation of the same, and

y Fig. 3 isa sectional front'view.

Fig. 4 is a section on the line 4- Fig. 3, with the key inserted intothe lock.

Fig. 5 is approximately a section on the line 55, Fig. 4.

Fig. 6 is a view similar to Fig. t but showing the position of the keywhen turned to unlock the bolt.

Fig. 7 is a view of the key detached.

Fig. 8 is an elevation of one of the wheels of the numbering mechanism.

a indicates the casing of the well-known slot mechanism used inconnection with gas meters and beneath which is a receptacle or drawer bfor the coins, the compartment a having arranged within it a rotatingmember or wheel 0 which receives the coins placed in the slot and whenoperated by the usual knob communicates motion to the shaft 0' sets themechanism of the meter (not shown) in a positionfor the delivery of thegas in a well known manner.

(Z is a lever which is depressed or operated by a coin as the wheel 0 isrotated, and the movements of which lever are communicated by ratchetand pawl mechanism (Z to the numbering mechanism 6 which is similar tothat described in the said former specification but arranged with theaxis of its shafts (Z in the same direction as the axis of the shaft 0instead of at right'angles thereto. This numbering mechanism is arrangedin the casing f, and on a frame or bracket 7' arranged within the saidcasing, is placed a bolt 7' which normally projects into a slot in thedrawer b. This bolt is adapted to be moved longitudinally to engage itwith or disengage it from the said drawer by means of a knob 9 having onit a pinion 9 which engages with rack teeth g on the said bolt. Theimproper movement of the bolt f is prevented by a lock which comprises abarrelor stud h rotatably mounted in a hole in said bolt, one section ofthis barrel being flattened as at 72), Figs. 3' and 4:, so that it can,when turned into coincidence with a slot 7L2 formed in the frame 7,slide longitudinally, but when turned at right angles thereto, as shownin Fig. 3, will not enter the said slot.

A key-way or slot 2' is cut through the barrel h which permits of theinsertion of a flattened key so that by turning the barrel through anangle of 90 the bolt f can be moved longitudinally with relation to theframe f and that when the barrel is turned so that the flattened portionis in the position shown in Fig. 3, the said bolt will be again lockedwith relation to the casing.

To secure the retention of the barrel h in the locked position I provideon its inner face an extension piece 2' having its ex tremity turned atright angles in alinement with the bolt f, as indicated at i Fig. 4,thus forming a stop to limit the distance that the key shall be insertedinto the said slot. This flanged end 2' is, however, cut away or notchedas indicated at i to permit the reception of spring actuated fingers orstrips j which engage the said notches and prevent the barrel from beingturned unless pressed back by the key is, Fig. 7, as indicated in Fig.4, the said key being cut with projections k, k which enter the notches2' to press back the said fingers 7'.

As with the locking arrangement an operator might unlock and open themachine without inserting the slips of paper to be printed I guardagainst this by mounting within the casing adjacent to the barrel h, awell balanced pivotal piece I so arranged with relation to the key slot2' that it will lie in front of one of the said fingers j, as shownclearly in Fig. 2, and when in this position prevent such spring fingerfrom being pushed back bv the key k so that the latter cannot beproperly introduced into the barrel until the said pivotal piece Z ismoved out of the path of the said spring finger.

The movement of the pivotal piece Z is effected by means of the paperslips, to allow of which the said pivotal piece has an arm Z whichprojects into the path of the slips the latter being introduced into thecasing through a guide tube m. To secure greater strength and rigidityin the paper slips to operate the pivotal piece Z, I propose to benddown the edges thereof and I therefore provide the groove or slot m withright angled extensions m, m into which the said bent down edges of thepaper sheets will enter.

The introduction of the paper slips as be fore described having allowedthe spring fi gers 7'. 7' to be pushed backward out of the notches i thebarrel 7?. can be turned to bring the fl t e ed peution it intoalinement with the slot 72, and therebv allow the bolt 7 to be withdrawnfrom engagement with the coin drawer so that the coins can be removed.is withdrawal of the bolt serves to effect the printing of the numberpresented u ermost bv the numbering disks by pulling down thef ame nwhich carries a pla en n to press the paper slips on o the said printingsurface.

To effect the downward mo ement of the frame n a lever 0 is pivot withinthe casing at 0 one end of which lever engages with the said frame as at0 while the other end enters a slot p in a cam-plate p fixed to the bolt7.

lVith this arrangement the withdrawing movement of the bolt f indicatedby the arrow, Fig. 3, causes the end of the lever o in the slot 12 tomove upward under the action of a cam surface 11* and then move againdownward to return the said frame at to its normal position. The camsurface 1) is formed upon a pivoted bar p so that when the bolt f ismoved in the opposite direction to that indicated by the arrow, Fig. 3,the roller on the end of the level 0 will pass under or out of contactwith the cam surface 19 so that no movement will be imparted to theplaten.

In order to provide that the key I: shall not be removed from the lockuntil the bolt f is replaced and the said key turned to lock the saidbelt, I provide a spring actuated finger g which forms one arm of a twoarmed spring secured to the lock barrel by a pin 9 When the barrel is inthe locking position, as indicated in Figs. 4 and 5,

this spring arm g bears upon a stop or abutment g so that the key can beinserted between the two arms of the spring, the lower arm thereofbearing against the underside of the key and being forced thereby out ofline with a stop g which normally obstructs the movement of the said armand consequently of the barrel if an attempt be made to turn the barrelwith an instrument other than the proper key.

When the key is inserted and the rotation of the barrel takes place, asindicated in Fig. 6, the arm q springs into a notch q and remains inthat position until after the bolt has been operated as hereinbeforederoe scribed and is returned to its normal position in which the springarm q rests upon the stop i out of engagement with the notch of the saidkey.

q indicates an additional notch in the key is which enables it to clearthe bracket or upright r carrying the stop and which bracket or uprightis fixed to the casing.

If for any reason the arm g-did not enter the notch g in the key 70 astop If on the bracket 7' and located above the said arm would preventit and consequently the barrel h from being rotated by the key.

In order that the operation of the bolt for locking the drawer shallreturn the number disks eto zero on the shaft d I arrange the which apawl M on a disk a fixed to the shaft 6 is designed to engage forrotating the said shaft and consequently the shaft 65 through the mediumof the wheels 3, 8

With this arrangement when the bolt f is drawn back clear of the coindrawer I) no movement will be imparted to the shaft (Z owing to thenotched disk u slipping under the pawl 24 when, however, the bolt ismoved in the reverse position, the movement of the shaft d will takeplace as before described.

The shaft d has formed in it a longitudinal ratchet groove 1) (Fig. 8)with which a pawl c on the several numbering disks 6 can engage in sucha manner that when the said shaft is rotated all the numbering diskswill be moved to the requisite distance as described in thespecification of my said former patent.

The usual spring actuated detent w in connection with each disk 6secures that the alinement of the several figures of the disks shall beperfect.

The operation of the machine is as follows z-JVhen a coin is insertedinto the machine and the coin wheel 0 has been turned by the operatingknob to automatically deliver the gas or other commodity, the numberingdisks are advanced one unit.

When .the .coins are to be collected the sheet or slip of paper (withcopy carbon if desired) is inserted into the slot m with its edgesturned down, as indicated by the dot ted lines in Fig. 2, which sheet ofpaper by contact with the arm Z moves the pivotal piece Z as beforedescribed, the key 70 can now be pushed into the slot 71 and the barrelh of the lock rotated to a position to free the bolt F. The collectornow withdraws the bolt from the coin receptacle Z) and at the same timebrings the platen n down on the paper to print and obtain a record ofthe number of coins together with the number of the articular machine.

The bolt f having been withdrawn the drawer b can be opened. Thereplacing of the said bolt to again lock the drawer auto matically setsthe disks 6 at zero, and when the bolt f is in its full locking positionth key can be removed from the lock.
